3. When calibration is finished, please turn off the power to store
data.
Before adjusting, please check if the power is enough and then
process the calibration.
When adjustment, please make sure the needles are suspended in
midair and with no contact on any object.

CARE AND MAINTENANCE

1. This instrument has the accurate temperature compensation
function, but if it is used in a place with high temperature or high
humidity, it will produce deference or an error message.
2. The sensor (needles) is the electric conduction element of
connecting the measured material. In order to avoid damage to
the instrument and electric shock, when the measured material
has voltage or static electricity, please clear the voltage or cut off
the power and then go to measure.
3. Please use the two needles to pierce into the material at the
same time and keep them for a while to get a more accurate
value.
4. For harder material or the material needing deep inspection,
please change to use the special needle (optional).
5. To avoid the incorrect reading, if the low symbol appears, please
replace the battery before using.
6. The sensor (needles) is the main element. If the sensor has
damage or other problems, please replace the new one to use
